Clamping band

Abstract

A clamping band comprising an ear part, a channel part, an extension pat and a hook part at an area where an external band part and an internal band part are overlapped, wherein the channel part comprises: a central part and two external parts divided by two strength-adjusting slots formed along a lengthwise direction of the damping band; a first stair part formed at the central part; and a second stair parts each slantly formed at a predetermined angle at two external parts along a direction the channel part enters into the central part, such that fastening power can be easily obtained by simple handling while length of material necessary for manufacturing the clamp band can be greatly reduced, thereby saving the material cost effectively.

What is claimed is:  
     
         1 . A clamping band, the band composed of an ear part, a channel part, an extension pat and a hook part at an area where an external band part and an internal band part are overlapped, wherein the channel part comprises: 
 a central part and two external parts divided by two strength-adjusting slots formed along a lengthwise direction of the clamping band;    a first stair part formed at the central part; and    a second stair parts each slantly formed at a predetermined angle at the two external parts along a direction the channel part enters into the central part.    
     
     
         2 . The clamp as defined in  claim 1 , wherein the extension part is provided with a slanted cut-out part corresponding in angle thereof to the second stair parts.  
     
     
         3 . The clamp as defined in  claim 1 , wherein hooks mounted at the hook part comprises: 
 hold part;    protrusive bent part successively formed at the hole part so as to be protruded from the outer surface of the clamping band;    protrusive hitching part protruded along the lengthwise direction of the clamping band from the protrusive bent part to the hole part; and    caved-in coupling pat formed at the protrusive bent part and the protrusive hitching part for the protrusive hitching part to be inserted into.
